We recommend using Globus when you need to transfer files between systems—between the resources that CISL manages and XSEDE facilities, for example. It has both web and command line interfaces, and its Globus Connect feature enables you to move files to and from laptop or desktop computers and other systems.
Globus is a robust, reliable alternative to GridFTP, with a typical transfer rate that ranges from 100 to 200 MBps. As a fire-and-forget utility, it enables users to start a transfer job and walk away. If a transfer fails, the system tries again and provides helpful feedback.
The installed Secure Copy Protocol (SCP) and Secure FTP (SFTP) utilities are best suited to transferring small numbers of small files to or from the resources that CISL manages.
These other tools also can be used to make secure transfers between your computer and our systems:
Also see the SCP and SFTP man pages on the computer from which you will initiate transfers.
BBCP is a multi-streaming utility for transferring large files. It splits files into multiple streams that are transferred simultaneously, so it is faster than the single-streaming SCP and SFTP utilities.
To transfer files to and from our tape-based High Performance Storage System, use the HTAR and HSI commands that are described in detail in our HPSS documentation. As noted there, transferring data between HPSS and computers that are outside the UCAR security perimeter requires two steps: Using HTAR or HSI to move files between HPSS and CISL's GLADE file spaces; then using another method such as Globus for transfers between GLADE and outside systems.
This service enables users of NCAR's GLADE storage and HPC systems for scientific computing to share files with colleagues and others who do not have NCAR user accounts.
Individuals who have GLADE access can copy files from GLADE and then share them with others via Google Drive or services such as DropBox and Amazon Web Services.
We recommend using the NCAR Data Sharing Service for sharing files, but the FTP server is available to authorized UCAR and NCAR personnel.
